Embodiment 1

[0053] Embodiment 1, medium closed circulation:

[0054] Such as figure 1 with Figure 4 As shown, the cold and heat exchange pipe 3 of the present invention is a closed circulation pipeline, and the water supply system 4 supplies water to the cold and heat exchange pipe 3 through the low-pressure automatic water replenishment control device 5, and the low-pressure automatic water replenishment control device 5. A booster pump 6 and a one-way valve 7 are provided.

[0055] Theoretically speaking, if it is a completely closed circulation pipeline, there should be no need to supplement the medium water flow, but considering the inevitable leakage, it should be supplemented with the medium water flow. The method of replenishment is: use the low-pressure automatic water replenishment control device 5 to replenish water into the circulation pipeline system, and when the water pressure in the pipe decreases, the booster pump 6 starts to work to replenish water; stop replenishing w...

Embodiment 2

[0058] Such as Figure 5 As shown, the cold and heat exchange pipe 3 of the present invention communicates with the water device 10 , and the water supply system 4 is a domestic tap water system 8 .

[0059] Under normal circumstances, the medium water flow of the cold and heat exchange pipe 3 is completely sealed as described in the above-mentioned embodiments, such as only supplying, heating or cooling of the air conditioner 11; but it may also occur that the medium water flow that needs to be directly used is very clean, At this time, the water flow is drawn out from the pipeline and sent to the water device 10 for direct use by the user. running water.

[0060] Because the cold and heat exchange pipe 3 is separated from the well wall of the ground source heat exchange well 1 by a certain distance, and the parallel pipelines are also separated by a certain distance, the cold and heat exchange pipe 3 needs to be supported in its transverse direction to prevent Deviation oc...

Abstract

The invention discloses a cold-heat exchange system for an underground water source, which comprises an underground source heat exchange well (1) and a heat pump (2), and is provided with a cold-heat exchange tube (3), wherein water in the cold-heat exchange tube (3) is isolated from the underground water source in the underground source heat exchange well (1), i.e. the water source is provided for the cold-heat exchange tube (3) by an individual water supply system (4); and the cold-heat exchange tube (3) is made of a corrosion-resistant heat conductive material. By the technical scheme, the heat exchange efficiency of the system is improved, the utilization ratio of the underground water energy source is improved, a heat transfer medium with superior water quality which can be directly used is obtained, the engineering investment and use cost are reduced, and sandstone, soil and toxic harmful substances in the underground water are prevented from affecting the environment, people and equipment.

Description

technical field [0001] The invention belongs to the technical field of renewable energy utilization, and relates to geothermal heat pump technology. More specifically, the invention relates to an underground water source cooling and heat exchange system. Background technique [0002] Ground source heat pumps use renewable energy stored in shallow layers of the ground to provide cooling and heating sources for building air conditioning. The temperature of the shallow water source under the earth's surface is relatively stable throughout the year, generally 10-25°C. It is higher than the ambient air temperature in winter and lower than the ambient air temperature in summer. It is a good heat source for heat pumps and cold sources for air conditioning. Water source heat pumps simultaneously It solves the cold and heat source of the air conditioning system and ensures the high efficiency and economy of the system. [0003] When the existing groundwater source heat exchange syst...
